10 -1 ROAD DIETS Before After Designing for Pedestrian Safety – Road Diets

10 -2 Learning Objectives At the end of this module, you will be able to: Describe how ped crash risk increases with number of travel lanes and speed.Describe how ped crash risk increases with number of travel lanes and speed. Explain why reducing # of travel lanes reduces risk, and makes it easier to cross the streetExplain why reducing # of travel lanes reduces risk, and makes it easier to cross the street Demonstrate how reducing lanes frees space for higher & better use:Demonstrate how reducing lanes frees space for higher & better use: Streets exist 24/7; peak traffic may be a concern for as little as 30 minutes a day Designing for Pedestrian Safety – Road Diets

10 -21 2.Which road produces the higher speed? With a 4-lane road a fast driver can pass others With a 2-lane road the slower driver sets the speed 3.Which road produces the higher crash rate? 4.Which is better for bicyclists, pedestrians, businesses? 1.Which road carries more traffic?

10 -22 Road Diet CMF = 0.71 (CRF = 29%) overall Designing for Pedestrian Safety – Road Diets Orlando FL
23
10 -23 What are some benefits of road diets for pedestrians? Reduce crossing distance Eliminate or reduce “multiple threat” crash types Install crossing island to cross in 2 simple steps Reduce top end travel speeds Buffer sidewalk from travel lanes (parking or bike lane) Reclaim street space for “higher and better use” than moving peak hour traffic Designing for Pedestrian Safety – Road Diets

10 -32 Road Diet Learning Outcomes You should now be able to: Describe how ped crash risk increases with number of travel lanes and speed. Explain why reducing # of travel lanes reduces risk, and makes it easier to cross the street Demonstrate how reducing lanes frees space for higher & better use: Streets exist 24/7; peak traffic may be a concern for as little as 30 minutes a day Designing for Pedestrian Safety – Road Diets
